This patch removes processing of CI votes. The reasons are:
* CI votes rely on DriverLog database which is deprecated
* CI votes are collected from comments to patch sets, querying
comments significantly increases the load on Gerrit
* CI votes are not actively used by community
* CI votes provide only partial look into state of third-party
drivers.
